Multivariate EGARCH model modifying egarch1.prg
Posted: Fri May 06, 2011 12:31 am
Hi, I am using eviews 6.0. I want to make volatility spillover analysis. I will estimate a multivariate EGARCH. My variables are rcds remt ri. I first ran a VAR model with two lags. Now I want to estimate the EGARCH effects for this system of equation. I read in the forums about this issue and you advice to modify the logl egarch1.prg object but I couldn't figure out how to modify it. Could you please help me on this issue it is really urgent? Also one more question if I use the EGARCH menu which is avaiable in the program already, seperately for each of the below equation I have written, can I find the the same result? And how about the conditional covariances? How can we apply BEKK to multivariate EGARCH?
The system of equation:
remt= c remt(-1) remt(-2) rcds(-2) rcds(-2) ri(-1) ri(-2)
ri= c remt(-1) remt(-2) rcds(-2) rcds(-2) ri(-1) ri(-2)
rcds= c remt(-1) remt(-2) rcds(-2) rcds(-2) ri(-1) ri(-2)
The system of equation:
remt= c remt(-1) remt(-2) rcds(-2) rcds(-2) ri(-1) ri(-2)
ri= c remt(-1) remt(-2) rcds(-2) rcds(-2) ri(-1) ri(-2)
rcds= c remt(-1) remt(-2) rcds(-2) rcds(-2) ri(-1) ri(-2)
